The price volume chart provides a graphical representation of historical trades in the selected market. This is known as a candlestick chart.
Price Volume Chart
Each candlestick provides the values for the open, high, low and close in the chosen interval.
Open, High, Low, Close Close Higher Close Lower Shadow
Blue candlesticks represent the price closing lower being than the opening price while white candlesticks represent the closing price being higher than the opening price. The candlestick’s shadow (or lines extending above and below the candlestick) represent when the high or low for the day were outside the range of the opening and closing price. Meanwhile, a flat line represents no movement between the opening and closing price.

The scroll bar at the bottom of the chart can be used to quickly change the time period/date displayed. Alternately the date selections at the top right can provide a custom date range to be visible.
